Finally got around to seeing this last night, sent the DVD back to Netflix too soon but there are a few vehicles missing... off the top of my head there's a Chevy Corsica that the main characters come into contact with, along with several other burned out hulks on the side of the road that might be hard to ID.

My review: Panic in the Year Zero was freaky, (but still fun, in a rather serious way) No Blade of Grass was scary (by the way I did see the ending, the opening was chilling), Soylent Green was frightening (especially the opening photo sequence, I've never bothered to watch it entirely), but this movie was heartwarming, and even special in way. A father and son story is more lovely than a whole family and a group of others surviving the very thing destroyed by the thoughtless ravages of man: our own home. But after all this time, this story is something to be loved in return.
